Abstract
An exact and reliable estimation of amine degradation, which can lead to significant problems, such as solvent losses, degradation by-products, fouling, foaming, corrosion, and increasing solution viscosity, is very important for development of innovative amines with higher chemical stability. In this study, thermal and oxidative degradations of aqueous N, N- Diethylethanolamine (DEEA) solution with CO 2 were investigated in a 600 mL stainless steel autoclave and compared with aqueous MEA solution. The results showed that DEEA solutions demonstrated a higher resistance to thermal degradation. The influence of key operating parameters, such as temperature, CO 2 loading, and DEEA concentration, on DEEA loss (mol%) were also investigated. In addition, the possible mechanisms of DEEA thermal degradation have been developed on the basis of the identified products.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
